Search for $B$ Mesogenesis at BABAR

BABAR Collaboration, J. P. Lees, V. Poireau +239

A new mechanism has been proposed to simultaneously explain the presence of dark matter and the matter-antimatter asymmetry in the universe. This scenario predicts exotic $B$ meson…

Search for an Axion-Like Particle in B Meson Decays

The BABAR Collaboration

Axion-like particles (ALPs) are predicted in many extensions of the Standard Model, and their masses can naturally be well below the electroweak scale. In the presence of couplings…

Search for Lepton Flavor Violation in $Υ (3 S) \to e^{\pm} μ^{\mp}$

BABAR Collaboration

We report on the first search for electron-muon lepton flavor violation (LFV) in the decay of a $b$ ~quark and $b$ ~antiquark bound state. We look for the LFV decay $Υ(3S)\rightarrow…
